How many articles do you click to read from your Facebook News Feed? Depending on how many articles your friends post on their timelines, many of the news stories and other articles you read could be coming through Facebook articles. In fact, for most online news and information sites their main source of readers these days is now Facebook.

That's a great way to catch up on interesting articles, but if you're using Facebook on a smartphone or tablet the experience can be a little awkward. You have to wait for the article to load on the site, and not every website is optimized for mobile. A lot of people quit halfway through and decide it's not worth it.

Facebook has noticed and decided to launch the "Instant Articles" system. This lets publishers send Facebook their stories that Facebook then provides on your timeline.

That way when you go to read an article, it loads right away. It can even include videos, moving images and large images for panning and zooming.

Publishers get to run their own ads and even sponsored content. They get full tracking and analytics to see how many folks are reading their articles. Plus, each publisher can have its own distinct visual identity so you know whose story you're reading. Add to that an audience of 1.3 billion people, and it's a publisher's dream.

But as with so many changes and improvements, there's just one problem.
